RFI CDX-TREME CDX5000 6.5dBi UHF CB 477MHz Extra Heavy-Duty Bull Bar Antenna 1200mm

RFI CDX-TREME CDX5000 6.5dBi UHF CB 477MHz Bull Bar Antenna with Oversized Heavy-Duty Spring

Maximum Range for Open Country and Highway Touring 

Built for drivers who need extended communication range across flat terrain, the RFI CDX-TREME CDX5000 combines higher 6.5dBi gain with a longer antenna design (1200mm) to deliver exceptional UHF CB performance where maximum distance matters most.  

Perfect for long-distance touring, road trains, highways, regional Australia and open landscapes, the CDX5000 provides stronger forward signal projection while maintaining the rugged durability expected from RFI's premium CDX-TREME range. 

Engineered specifically for 4WDs, commercial vehicles, touring rigs and fleet applications, this heavy-duty bull bar antenna features RFI's patented Meander™ PCB technology for outstanding RF performance and reliable communications across the Australian 477MHz UHF CB band.

Designed for Long-Distance UHF Communication

When travelling across highways, rural properties or Australia's expansive outback, a higher gain antenna provides improved communication over greater distances in relatively flat terrain.

The CDX5000 is ideal for:

• Highway touring
• Long-distance convoy driving
• Regional Australia
• Open country
• Agricultural properties
• Mining operations
• Commercial transport
• Fleet vehicles

Advanced Australian Antenna Engineering

Unlike traditional wire-wound antennas, the CDX5000 incorporates RFI's patented Meander™ PCB collinear technology to provide:

• Higher gain consistency
• Excellent radiation efficiency
• Stable signal performance
• Superior mechanical strength
• Reliable long-range communications

Designed and manufactured in Australia, every antenna is engineered to perform in demanding environments where dependable communications are essential.

Heavy-Duty Construction Built for Extreme Conditions

The CDX-TREME series has been purpose-built for Australia's harshest conditions.

Featuring an oversized heavy-duty spring assembly, reinforced ferrule architecture and secure removable whip, the CDX5000 is designed to withstand:

• Continuous vibration
• Corrugated roads
• Harsh off-road environments
• Commercial fleet use
• Agricultural applications
• Mining conditions

The oversized spring helps protect the antenna from impacts while reducing stress on the mounting point during rough terrain.

Choose the Right Gain for Your Driving

Unlike lower-gain antennas designed for mixed terrain and hilly environments, the 6.5dBi CDX5000 is optimised for:

• Longer communication distances
• Flat and open terrain
• Highway driving
• Rural and regional travel
• Open country touring

If your travels regularly take you across Australia's highways, inland roads or wide-open landscapes, the higher-gain CDX5000 offers the performance advantage you're looking for.
